BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a laser aiming device which makes use of two adjusting screws and a spring blade jointly to form a three-point supporting and positioning apparatus. Moreover, planes corresponding to the rotating adjusters are provided on the aimer to reduce dislocation and deviation of the aimer during the aiming process so as to enhance the accuracy of the aimer.

2. Description of Related Art

In order to sharpen the accuracy, the laser aiming device is mounted on the gun barrel using the high convergence and low attenuation characteristics of laser beam. However, the device must be zeroed-in each time it is mounted onto a gun. This is achieved by calibration to synchronous laser beam with the point of impact of the gun so as to fully enhance the accuracy.

As shown in FIGS. 1, 2, the conventional gun aiming device comprises a base housing a having a through hole a1 in the aiming direction, a laser module b of a cylindrical shape, two adjuster screws including vertical rotating adjuster c, and horizontal rotating adjuster d. The laser module b is held in place by the two adjusting screw c, screw d and the elastic blade 5.

However, the conventional structure has a main drawback in practical use; the cylindrical structure of the laser module limits the maneuverability of the laser module in calibration.

Referring to FIG. 2, a user (not shown) rotates the vertical rotating adjuster c and the vertical rotating adjuster c turned upward to push the aimer b moving upward. By the force of the elastic blade 5 effecting on the aimer b, the aimer b will move against the horizontal rotating adjuster d following the arc of the aimer b. Therefore, for conventional gun aiming device, it is necessary to turn the horizontal adjuster c and the vertical adjuster d simultaneously to make the aimer b to move vertically or horizontally. Moreover the cylindrical structure of the module has a highest point f, g on each side horizontal and vertical respectively. Therefore, when the vertical rotating adjuster c is depressed for vertical adjustment, user must exercise carefully not to pass the module beyond the highest point f of contact, if the user does, the horizontal adjuster d will block the module's returning passage. Vise versa, if the user adjusts the horizontal adjuster d for horizontal direction. The position of the vertical rotating adjuster c will block the returning passage of the module in the same manner because of the highest point g.

Accordingly, in consideration of the above drawback in practical use of the conventional laser aiming device, the present invention aims is to provide a gun aiming device to solve the above problems in the prior art.

SUMMARY OF THE INVENTION

The primary object of the present invention is to change the module structure to have two flat surfaces to improving a un-block passing way of the aimer. The structure provides no highest points to allowing the adjusters return to their original position without any obstacle blocking each other's returning passage.

Moreover, the structure defined on the aimer is used to reduce dislocation and deviation of the aimer during the aiming process so as to enhance the accuracy of the aimer.

Another object is to provide the structure of two flat surfaces that a user can rotate only one adjuster to make a calibration of the aimer on vertical or horizontal axis independently.

Features of the invention useful in accomplishing the above objectives include, a first plane disposed on one side of the aimer and a second plane disposed on the other side of the aimer perpendicular to the first plane. The first rotating adjuster penetrates one side of the positioning base body, and the distal end of the first rotating adjuster exactly abuts against the first plane of the aimer. The second rotating adjuster penetrates one side of the positioning base body, and the distal end of the second rotating adjuster exactly abuts against the second plane of the aimer. The elastic blade is disposed at a side end in the through hole, and the distal end of the elastic blade exactly abuts against the aimer. The elastic blade is exactly located at a side corresponding to the first and second rotating adjusters to jointly achieve three-point supporting and positioning of the aimer.

In the above structure, the first rotating adjuster and the second rotating adjuster are adjusted respectively for horizontal-axis motion and vertical-axis motion of the aimer to calibrate the central position of the aimer.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As shown in FIGS. 3, 4 a gun aiming device of the present invention comprises a positioning base body 1, an aimer 2, a first rotating adjuster 3, a second rotating adjuster 4, an elastic blade 5. The positioning base body 1 has a through hole 11 axially penetrating it. The through hole is rectangular. A first adjusting hole 12 and a second adjusting hole 13 axially perpendicular to the through hole 11 are disposed at two vertically adjacent sides of the positioning base body 1, respectively.

The aimer 2 has a circular cylindrical shape, and is installed in the through hole 11. A first plane 21 is disposed at the bottom side of the aimer 2. A second plane 22 perpendicular to the first plane 21 is disposed at the right side of the aimer 2.

The first rotating adjuster 3 is a screw, and is locked from the outer end of the positioning base body 1 into the first adjusting hole 12. The distal end of the first rotating adjuster 3 has a circular arc-shaped first contact surface 31 that correspondingly contacts the first plane 21 of the aimer 2.

The second rotating adjuster 4 is a screw, and is locked from the outer end of the positioning base body 1 into the second adjusting hole 13. The distal end of the second rotating adjuster 4 has a circular arc-shaped second contact surface 41 that correspondingly contacts the second plane 22 of the aimer 2.

The elastic blade 5 is disposed at a side end in the through hole 11. The distal end of the elastic blade 5 has an abutting surface that exactly abuts against the aimer 2 and is exactly located at a side corresponding to the first rotating adjuster 3 and the second rotating adjuster 4 to jointly achieve three-point supporting and positioning of the aimer 2.

As shown in FIGS. 3, when the user (not shown) wants to perform vertical calibration of the aimer 2, the user can turn the first rotating adjuster 3. When the rotating adjuster 3 is turned upwards, the first contact surface 31 of the first rotating adjuster 3 will push upwards and hold the first plane 21 of the aimer 2 to move the aimer 2 upwards along the vertical axis and also push the abutting surface 51 of the elastic blade 5 so as to cause deformation of the elastic blade 5, thereby accomplishing balance and positioning of the aimer 2. When the first rotating adjuster 3 is turned downwards, the first contact surface 31 of the first rotating adjuster 3 will retreat downwards. Because the supporting force under the aimer 2 decreases, the aimer 2 will move downwards along the vertical axis due to the push of the abutting surface 51 of the elastic blade 5 until the first plane 21 of the aimer 2 is supported by the first contact surface 31 of the first rotating adjuster 3 again, thereby accomplishing balance and positioning of the aimer 2. Through the above adjustment process, the vertical calibration of the aimer 2 along the vertical axis can be accomplished. During the adjustment process, although the second plane 22 of the aimer 2 synchronously moves vertically, it still maintains contact with the second contact surface 41 of the second rotating adjuster 4. Therefore, the position of the vertical axis of the aimer won't be affected, and it is unnecessary to adjust the second rotating adjuster 4.

As shown in FIGS. 4, when the user wants to perform horizontal calibration of the aimer 2, the user (not shown) can turn the second rotating adjuster 4. When the rotating adjuster 4 is turned leftwards, the second contact surface 41 of the second rotating adjuster 4 will push leftward and hold the second plane 22 of the aimer 2 to move the aimer 2 leftwards along the horizontal axis and also push the abutting surface 51 of the elastic blade 5 so as to cause deformation of the elastic blade 5, thereby accomplishing balance and positioning of the aimer 2. When the second rotating adjuster 4 is turned rightwards, the second contact surface 41 of the second rotating adjuster 4 will retreat rightwards. Because the supporting force at the right side of the aimer 2 decreases, the aimer 2 will move rightwards along the horizontal axis due to the push of the abutting surface 51 of the elastic blade 5 until the second plane 22 of the aimer 2 is supported by the second contact surface 41 of the second rotating adjuster 4 again, thereby accomplishing balance and positioning of the aimer 2. Through the above adjustment process, the horizontal calibration of the aimer 2 along the horizontal axis can be accomplished. During the adjustment process, although the first plane 21 of the aimer 2 synchronously moves horizontally, it still maintains contact with the first contact surface 31 of the first rotating adjuster 3. Therefore, the position of the horizontal axis of the aimer won't be affected, and it is unnecessary to adjust the first rotating adjuster 3.

To sum up, the present invention has the following advantages:

-   1. The present invention makes use of an elastic blade 5 and two     rotating adjusters 3 and 4 to achieve three-point supporting and     positioning of the aimer 2. Regardless of whether the horizontal     calibration or the vertical calibration of the aimer 2 is performed,     it is only necessary to adjust the first rotating adjuster 3 or the     second rotating adjuster 4. The operation is simple, and accurate     calibration can be easily accomplished. -   2. The aimer 2 has a first plane 21 and a second plane 22. When the     first rotating adjuster 3 is turned by itself to perform the     vertical calibration of the aimer 2, the aimer 2 can still maintain     balance with the second rotating adjuster 4. No dislocation or     deviation will be caused, and it is unnecessary to adjust the second     rotating adjuster 4. Moreover, because of the design of the second     plane 22, the second rotating adjuster 4 will not block the way on     which the aimer 2 returns back to original position. Similarly, when     the second rotating adjuster 4 is turned by itself to perform the     horizontal calibration of the aimer 2, the aimer 2 can still     maintain balance with the first rotating adjuster 3. No dislocation     or deviation will be caused, and it is unnecessary to adjust the     first rotating adjuster 3. With no doubt, the first rotating     adjuster 3 will not block the aimer 2 to return the original     position because of the first plane 21 -   3. The elastic blade 5 has an abutting surface 51, the first     rotating adjuster 3 has a first contact surface 31, and the second     rotating adjuster 4 has a second contact surface 41. The elastic     blade 5, the first rotating adjuster 3 and the second rotating     adjuster 4 only maintain point-wise or line-wise contact instead of     plane-wise contact with the aimer 2 to reduce unwanted influence     such as dislocation and deviation of the aimer 2 during the     calibration process, thereby enhancing the accuracy of the aimer 2.

Various substitutions and modifications have been suggested in the foregoing description, and others will occur to those of ordinary skill in the art.
